remoteproc: enable core dump and halt-on-crash for dsp
Support for halt-on-crash feature is enabled for dsp. The
generation of code dump file is also enabled for dsp. DSP
memory can be pulled from following file for offline
analysis:
/d/remoteproc/omap-rproc.0/core
Currently dsp registers are not saved. The DSP IO buffer
area is skipped as per core-dump design.
